Key result
A 40-year-old male with an anomalous origin of the right coronary artery from the left sinus of Valsalva presented with persistent asymptomatic tachyarrhythmia and a progressive decline in LVEF to 20%.
Why the study?
Diagnosing ectopic coronary artery origin is critical due to its link to sudden cardiac death in young populations and its potential to cause myocardial ischemia, fibrosis, and fatal ventricular arrhythmias.

This case highlights a rare presentation of an anomalous right coronary artery originating from the left sinus of Valsalva, associated with asymptomatic tachyarrhythmia-induced cardiomyopathy.

May prompt evaluation for anomalous coronary origins in unexplained tachyarrhythmia with cardiomyopathy; hypothesis-generating and requires confirmation in larger cohorts.
The anomalous origin of the coronary artery is a relatively uncommon condition with a variant incidence depending on the modality of the imaging techniques such as transesophageal echocardiography (TEE), computed tomography angiography (CTA), magnetic resonance angiography (MRA), or invasive coronary angiography (ICA). The importance of diagnosing ectopic coronary artery origin comes from its possible relation to sudden cardiac death (SCD) cases in young populations. The anomalous origin of the coronary artery could cause myocardial ischemia and fibrosis; this would, in turn, increase the chances of fatal ventricular arrhythmias. In this report, we present a 40-year-old male, incidentally found to have persistent tachycardia and a gradually decreasing left ventricular ejection fraction (LVEF). He denied any symptoms or changes in his baseline, unlimited, functional capacity. However, his records were remarkable for persistent tachycardia over more than six months, raising concerns about tachyarrhythmia-induced cardiomyopathy related to his anatomical variations. We also discussed the guideline-directed therapeutic option for the abnormal origin of the coronary artery as per current guidelines.
